Not trying to hijack Fox's thread (he has me on ignore anyway) but it is this Kenny below which is why Fox went with the genuine USA made Johnson short travel hydraulic roller lifters. Kenny's green camaro went 3.97 in the 1/8 mile on a 388ci hydraulic roller LS with cathedral heads with out the box Johnson hydraulic lifters and BTR camshaft. Kenny has had several turbo LS cars before this one in the low 7's, high 6's 1/4 mile, and all of his builds have used simple off the shelf parts (with Johnson hydraulic lifters), nothing really exotic. And i know he also used Rotella 15/40 oil in them in the past. He was always willing to share info and all of his combination back when he'd post on the ls1tech forum. His past builds are still posted on there. He is just finishing up a brand new engine build, it'll be interesting (to me at least) to see if the extra CI and LS7 heads gain, over his previous 388ci and cathedral headed builds ..
